lclaim.

My invention relates to an improved surgical dressing, and its object isto provide a dressing which may be easily applied to and removed from awound with a minimum of discomfort to a patient. a

I accomplish this object by constructing the dressing of an orificedlayer of adhesive plaster, a ring of resilient material about theorifice adjacent that face of the plaster to be applied to the wound, alayer of dressing material covering the orifice in the plaster and asecond layer or piece of plaster over the layer of dressing material.

One embodiment of the invention is illustrated in the accompanyingdrawing, in which Fig. 1 is a sectional view of my improved surgicaldressing, and

Fig. 2 shows it as seen from above.

A plaster 3 pasted on the wounded part 1 of the body 2 is provided withan opening 4 in reach of the wound 1. The opening 4 is bounded by a ring5 of resilient material. Above the opening 4 of the plaster 3 thereispasted a covering 6 which carries a layer 7 of dressing material.

In using the dressing the plaster 3 is applied to the body so that theopening 4 coincides with the wound 1. Then the covering piece 6 carryingthe dressing 7 is placed upon the plaster after the wound has beentreated with the necessary drug.

For treating the wound it is merely necessary to remove and renew onlythe covering piece 6 which causes no pain to the patient because thispiece is only applied to the plaster 3. The'covering piece 6 isprevented by the ring 5 from touching the wound, and consequently thewound which is probably alreadv covered with a scab or healing cannot betorn open again by the taking off of the coilering piece 6. The distanceof the covering piece 6 from the wound offers the further greatadvantage that the healing procedure is much quicker and easier.

Consequently the wound 1 can be surveyed and cleaned in the most simplemanner as often as required without any pain or other discomfort to thepatient.

What I claim is:

A surgical dressing comprising an adhesive plaster having an openingtherein, a ring of resilient material engaging a face of the plaster 76about said opening, a layer of dressing material overlying said openingon the opposite face of the plaster and a second adhesive plasteroverlying said dressing material and removably attached to the firstplaster.
